UNITED STATES PATENT OFFICE,

HENRY PRICE BALL, 0F PITTSFIELD, MASSACHUSETTS, ASSIGNOR TO -GENEI%AL ELECTRIC COMPANY, A CQRPORATION OF NEW YORK L ELECTRIC HEATER r'o'n snamne wex AND r m LIKE.

This invention relates to devices for heating material such as sealin wax and the like, and has for its object t 1e provision of a device of this character which will he sim ple in. construction and at the same time reliable and efiicient in operation.

One of the objects of my invention is to provide a heater for sealing wax or the like in which the wax is used as fast as it is melted so that there will be no repeated reieating of the wax which would cause it. to change its nature by driving out its volatilizing properties and leaving a gummy residue which very difficult to melt.

In carrying out my invention I provide a heater of this character in which the heating element is entirely separate from the-stick of wax t be melted, the arrangement being such that the waXto be melted is moved into contact with the heating element and then moved out of contact when a sufficient quantity has been melted.

In one embodiment of my invention I provide a melting .pan for the wax which is normally out of contact with the heating. element but which Is moved into contacttherewith when the wax is to be heated. The arrangement is such that the wax flows out of the pan while it is being melted, so that therewill never be any of the wax left in the pan and the pan will not be left in contact with the heating unit to be continually reheated and caused to smoke and burn the pan Other objects and purposes of my invention will a pear in the course of the following specification, in which I have shown my invention embodied in concrete form for purposes of illustration.

Referring to the drawings illustrating my invention, Figure 1 is a side elevation of my complete device; and Fi 2 is a plan view of the same.

Referring to the drawhigs, 10 represents the electrically heated elei'cent tor melting the scaling wax or the like. The particular Specification of Letters Iatent. a lication filed; m 10, ran.

construction whereby this: element is heated forms part of myinvent-ion. For purlustration, I have shown a unit which may be of copper or other metal havat an angle there.-

the element 10 is inside of the casin l3 and current is conducted to the heating unit 13 by means of wires 14 passing up inside of the tube 11. 15 is the heat'ng pan for the sealing wax. This pan, in the form shown in the drawing, is provided with a-spout at 16 for permitting the sealing wax to run out. At its rear end the pan is provided with two arms 17 by which the pan is pivoted to the support at 18. The pan normally held out of contact with the unit in any suitable manner, as, for instance, by )roviding countcrweights 19, as shown in the drawing, although, of course, any other means for producing this result may be employed without departing from thespirit of my invention.

In order that the heating pan may always be brought down into uniform contact with the heating unit, that is, in contact throughout the surface of the pan, I have provided a loose connection at the pivot 18. This I have done by making the elongated slot 20 for the pivot. This provides a certain amount of lost motion and will enable the pan to assume the desired position in contact a with the heating unit.

In operation, the operator, desiring to melt the sea ling wax, inserts the stick of was 21 into the heating pan and forces the latter down into contact with the heating unit, as shown in dotted lines in Fig. 1. The heat is quickly co-nnnunicated through the pan to the wax, which melts and runs out through the spout 16 on to the surface to be sealed. As soon as the desired amount of wax is run out the operator removes the stick of wax and allows the pan to assume its normal position. In this position there will be practically no wax left in the pan, and, since the pan is not in contact with the heating unit, there will be no burning of the pa or sinok; ing due to the slight amount of residi'ie lei't in the pan. It is obvious, of course, that my invention may bl employed IQQULQI t mg a good thermal conductivity mounted EIIIPQII a support 11. This support may be a fixed tubular support mounted upon the base 12 and bent in the form of a goose neck so that the unit will stand with. The electric heating unit for heating materials than sealing wax, such as solder and the like.

\Vhile I have described my invention as embodied in concrete form and as operating in a specific manner for purposes of illustration, it should he understood that I do not limit myself thereto, since Various modifi rations thereof will suggest themselves to those skilled in the art without departing from the spirit of my invention, the scope of which is set forth in the annexed claims.

lVhat I claim as new, and desire to secure .h v Letters Patent of the United States, is

1. A heater for sealing war or the like comprising an electrically heated elementand a pivoted heating pan biased to assume a horizontal position out of engagement with said element and arranged to be i'i'ioved into an inclinedposition engaging the element.

2, In a heater for sealing wax or the like, a heating element, a. pan mounted. adjacent said heating element so that it may he pressedinto good thermal relation therewith and automatic means for moving said pan away from said heating means upon removal of such pressure.

3. A device for melting sealing wax or the like comprising a mass "of good heat conductivity, heating means for the same, a pan In witness whereof, I have hereunto set' my hand this 6th day of May, 1911.
